Drilling Engineering
With advanced drilling technology service capabilities, professional project management team and operation team, we have the ability to handle complex situations.
Technical team and advantages
The company has a series of equipment from 2000m vehicle-mounted drilling rigs to 7000m drilling rigs. It has the ability to independently complete conventional deep wells, adjustable wells, horizontal wells, directional wells and clump directional wells, and has the experience of drilling and construction of small wellbore wells, complex and deep horizontal wells, branch wells, and large displacement wells, and can complete various special drilling construction under various complex conditions.
Technical Advantages
01
Special well type for construction
Ultra-deep high-temperature, high-pressure horizontal well, bottom-hole temperature up to 150℃, formation pressure up to 97MPA
Fish bone branch well, horizontal 5 branches, vertical 3 branches
Fine pressure control, and achieve near-balanced drilling through fine pressure control technology
Double step-stage horizontal wells to realize the mining of different reservoirs
Thin oil layer, the thickness of the production layer is only 0.5 meters. Through precise guidance such as near drill bit, azimuth, and drilling resistance, the oil layer penetration rate reaches 90%.
Extra-long horizontal section drilling technology, horizontal section drilling length up to 2550 meters
02
Selected mud system for drilling and encountering complex formations
The huge thick salt paste layer uses anti-pollution saturated salt cement slurry system technology to effectively curb complex situations such as salt paste layer flow, salt layer creep, well diameter expansion, necking, formation collapse, etc.
03
Drilling speed up
(1) Mechanical speed-up: select high-efficiency drill bits and drilling tools design, and optimize the performance and structure of drilling equipment;
(2) Drilling fluid speed up: efficient drilling fluid formula to improve drilling fluid performance, improve drilling fluid circulation efficiency and well wall stability;
(3) Speed up drilling process: use underbalanced drilling and other technologies to reduce the drilling down time and optimize reasonable drilling parameters;
(4) Tool speed-up: The use of torsional impulse tools effectively solves the problem of difficulty in sliding drilling and drilling pressure transmission, greatly ensuring underground safety and drilling efficiency.
